outline-effect

An outline effect made with threejs'postprocessing library. It uses sobel edge detection to verify edges in the depth and normal textures of the scene.

stuff that needs work, but i'm too lazy to do right now...

• Depth texture edge detection causes aliased lines, needs smoothing. Note: passing in resolution * devicePixelRatio makes this better. Adding an <SMAA> pass makes it smooth as butter! Although I feel like this is expensive...

• Could use a surface ID textures for better lines as outlined here.

• Thin/faded lines are far distances (use depth texture to do this)?
